Install
Skills CLI
npx skills add Scripter36/InstantMimic
Asks which skills and agents to install. Just one: npx skills add Scripter36/InstantMimic --skill config-variant-check — add -g for every project.
Claude Code
git clone https://github.com/Scripter36/InstantMimiccp -r "InstantMimic/plugins/instantmimic-workflows/skills/config-variant-check" ~/.claude/skills/
Copies the config-variant-check skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add Scripter36/InstantMimic
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
config-variant-check
Use when adding, editing, or reviewing Hydra config variants in this repository.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ config-variant-check/ SKILL.md -
experiment-report
Use when summarizing experiment results, comparing seeds, preparing tables, or reporting playback rewards and videos.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ experiment-report/ SKILL.md -
instantmimic
Set up and use InstantMimic for physics-based reinforcement learning from a natural-language goal, including when no repository is present. Acquire the public source, prepare models and environments, train, evaluate, render, or perform bounded optimization. Use for InstantMimic tasks; do not redirect unrelated RL projects to this framework.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ instantmimic/ SKILL.md -
migrate-external-env
Migrate or audit an IsaacLab, Isaac Lab, mjlab, or other external simulation and reinforcement-learning environment in InstantMimic. Covers source discovery, behavioral contracts, assets, implementation, learning/evaluation integration, production optimization, evidence, and independent review.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ migrate-external-env/ SKILL.md -
ncu-profile
Use when inspecting a specific CUDA kernel's occupancy, memory throughput, stalls, or source-level metrics with Nsight Compute.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ ncu-profile/ SKILL.md -
nsys-profile
Use when profiling end-to-end training or playback timeline, CUDA API overhead, NVTX ranges, or CPU/GPU launch behavior with Nsight Systems.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ nsys-profile/ SKILL.md -
optimize-runtime
Iteratively optimize a specified workload by choosing suitable metrics and diagnostic tools, making causal code changes, remeasuring and validating outputs until no actionable axes remain. Use for sustained CPU, GPU, renderer, training, I/O or memory optimization; use a profiling skill for a single capture and tune-hyperparameters for learning-parameter search.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ optimize-runtime/ SKILL.md -
play-best
Use when evaluating a checkpoint, finding a best checkpoint, generating playback video, or extracting playback reward and episode length.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ play-best/ SKILL.md -
review-external-env-migration
Independently review a completed external environment migration from a strict raw evidence packet. Use only in a fresh context with no implementation conversation when judging InstantMimic migration gates, especially semantics, lifecycle, learning/evaluation, and native-device optimization.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ review-external-env-migration/ SKILL.md -
smoke-run
Use when validating wiring, Hydra composition, train/play startup, or a small sanity check before a larger experiment.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ smoke-run/ SKILL.md -
train
Use when training a policy in this repository, constructing train commands, or choosing train overrides.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ train/ SKILL.md -
tune-hyperparameters
Derive and run bounded, training-only Pareto HPO for an InstantMimic environment, especially after migration. Use when selecting a safe parameter whitelist and blacklist, calibrating active-training-time and evaluation budgets, comparing learning quality against speed, or running the search locally or through SSH and Slurm.
plugins/instantmimic-workflows/ on GitHub (opens in a new tab)skills/ tune-hyperparameters/ SKILL.md

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
